中文摘要：
对国内外近年来关于大跨度空间结构的抗火研究进行了系统的综述与分析.论述了大空间建筑火灾模型和温度场的研究内容,介绍了大空间建筑火灾中钢构件升温的计算方法,说明了大跨度空间结构所用材料的抗火性能,详细阐述了火灾高温作用下一些大跨度空间结构体系的抗火性能,并对目前性能化的抗火设计方法及其在工程中的应用做了介绍与总结,最后指出了尚存在的问题及需要进一步研究的工作.
英文摘要：
The main progress in research on fire-resistance of long-span spatial structures in recent years is summarized and analyzed systematically in this paper.Firstly,temperature field of long-span spatial structures under fire conditions is presented,as well as the algorithm of steel member at elevated temperature in large space fire.Then,the behavior of materials and some kinds of long-span spatial structures under fire condition are illustrated in details.Furthermore,the performance-based design for the fire-resistance of long-span spatial structures and some applications are summarized.Finally,the remained problems and the key problems for further research are pointed out.
